The Claim
Passive back exosuit use during repetitive lifting tasks in healthy adults is associated with a 15–22% reduction in surface electromyography (sEMG) activity in the erector spinae and quadriceps muscles.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When healthy adults use a passive back exosuit during repetitive lifting, the electrical activity in their lower back and thigh muscles decreases by 15–22%.
See the scientific wording
Passive back exosuit use during repetitive lifting tasks in healthy adults is associated with a 15–22% reduction in surface electromyography (sEMG) activity in the erector spinae and quadriceps muscles, suggesting a biomechanical effect that may reduce muscular effort during sustained lifting.
The exosuit pulls on the lower back and hips during lifting, taking some of the weight off the muscles. This means the back and thigh muscles don't need to contract as hard to lift the same load, so they use less energy and produce less electrical activity.
What the research says
1 studyStudy: Biomechanical Analysis of Repetitive Lifting with Passive Exosuit Assistance: Preliminary Results
Wearing this back support suit while lifting things over and over made the back and thigh muscles show less electrical activity—meaning they didn’t have to work as hard, just like the claim says.
